To the full extent permitted by law, the present United States Non-provisional Patent Application hereby claims priority to and the full benefit of, U.S. Provisional Application No. 62/650,341, filed on Mar. 30, 2018, entitled “Quick Class Room Door Lock and Methods of Use”, which is incorporated by reference herein in its entirety.
The present disclosure is directed to a closure fastener and methods of use thereof. More specifically, the present disclosure is directed to a two part lock accessory adapted to be manually installed on the inside of a frame and a sliding holding member preventing unauthorized opening of the door.
Various approaches have been utilized to lock a door using a safety lock for securing the door to a frame to prevent opening from the outside. For example primary lock assemblies utilize a bolt that extends horizontally between the door and frame across the swinging edge of the door. One such previous primary approach includes a handle driven spring latch lock which uses a spring to hold the latch in a slot bored into the front face of a door jamb to keep the door closed. One disadvantage or drawback to this approach is that, retraction of the latch may occur by wedging a tool into the gap and prying the spring held latch enabling retraction of the bolt itself. Another previous primary approach includes a deadbolt, which uses a key or inside lever to rotate or move the bolt in a slot bored into the front face of a door jamb to keep the door closed. One disadvantage or drawback to this approach is that, these devices are difficult to install in that they require internal drilling of the door as well as of the frame for mounting requiring corresponding aligned holes being drilled in the frame and the door edge. Another disadvantage is that the door can easily be kicked in if the frame is made of wood because the deadbolt acts as a device that splits the frame.
Additionally, secondary lock assemblies include a door chain or security chain lock or hinged lever, which uses a small chain with a small knob attached to one end that can be moved into or out of a receiving channel of a door plate or a hasp, which is a slotted hinged metal plate that forms part of a fastening for a door and is fitted over a metal loop or swivel eye on the frame and turned in a locked or unlocked position. The hasp may be secured by a pin or padlock to keep the door closed or limited opening. One disadvantage or drawback to this approach is that, the small chain or lever attached to the door can be cut with a cutting tool since it is visible during limited opening of the door.
Another previous secondary lock assembly includes a plate mounted to the front face of the frame or door jamb between the door and the frame facing the closed door and extending horizontally into the interior. The interior section includes a hole to receive a threaded bolt or clasping pin crosswise to the plate and when inserted the bolt or pin blocks the door from swinging open by contact with the swinging door up against the bolt and holds the door closed. One disadvantage or drawback to this approach is that, lock assembly holding power against a large force causes the secondary lock assembly to twist or pivot possibly freeing the door from the bolt and not keeping the door closed and locked. Another disadvantage or drawback to this approach is that, a threaded bolt or clasping pin takes additional time to position and lock the secondary lock assembly. Yet another disadvantage or drawback to this approach is due to the limited material thickness of the door and door frame, such devices can be forced open if sufficient force is applied to the door.
Therefore, it is readily apparent that there is a need for a door lock assembly that can be easily installed by the occupant when extra door lock protection is required, which is extremely difficult to forcibly break away from the door and door frame and maintain holding power against a large force, which will not present an unsightly appearance when not in use, which is simple enough to operate by a school age child, which is of a relatively inexpensive construction, and which can be installed with a minimum of labor and expense. The instant disclosure is designed to address at least certain aspects of the problems or needs discussed above by enabling a two part lock accessory adapted to be manually installed on the inside of a frame or wall and a sliding holding member which prevents unauthorized opening of the door.
Briefly described, in an example embodiment, the present disclosure may overcome the above-mentioned disadvantages and may meet the recognized need for a door lock assembly for a door hinged to a door frame, having primarily a two-part lock assembly, including a linear pin or bolt having a first pin end and a second pin end, the second pin end formed with a handle attached and a magnet positioned therearound the second pin end and proximate a junction between the handle and the second pin end and a mounting plate having a first plate end and a second plate end, the plate ends having one or more mounting holes, the mounting plate having a base or humped body positioned between first plate end and a second plate end, the humped body having a locking aperture positioned crosswise there through the humped body to receive first pin end and, thus, functions to be easily installed by the occupant when extra door lock protection is required, which is extremely difficult to forcibly break away from the door and door frame and maintains holding power against a large force, which will not present an unsightly appearance when not in use, which is simple enough to operate by a school age child, which is of a relatively inexpensive construction, and which can be installed with a minimum of labor and expense.
Accordingly, in one aspect, the present disclosure may include a pin keeper having a cover and a backplate with a plurality of mounting apertures and two or more pin supports mounted on the backplate, the two or more pin supports having a support aperture there through to receive the first pin end therein to store the pin when not in use. One of the two or more pin supports may be formed of an iron or metal material wherein the magnet's attraction holds the handled pin therein the two or more pin supports.
Accordingly, in another aspect, the present disclosure may include an alarm system having a power supply, an alarm, and a contact switch, in a normally closed state positioned in electrical communication with each other, to receive the first pin end therein the pin keeper to deactivate or open the switch but on removal of the pin the switch closes and activates the alarm system.
Accordingly, in another aspect, the present disclosure may include a set of slotted u-shaped door hinge supports fabricated to fit around a door hinge to reinforce the hinge side of the door.
Accordingly, in another aspect, the present disclosure may include mounting hardware to secure the mounting plate to the door or door frame, to secure the pin keeper to an adjacent wall, and to mount the door hinge supports.
In an exemplary embodiment of the door lock assembly to secure a door having hinges between the door and a door frame positioned in a wall, the door lock assembly including a pin having a first pin end and a second pin end, the second pin end formed with a handle attached thereto and a magnet positioned proximate a junction between the handle and the second pin end, and a mounting plate having a first base plate end and a second base plate end, the first base plate end and the second base plate end having one or more base attachment apertures to affix to the door frame, the mounting plate having a midsection positioned between the first base plate end and the second base plate end, the midsection having a locking aperture positioned crosswise therethrough to receive first pin end, the first pin end pass therethrough the locking aperture until the magnet contacts the mounting plate, and the first pin end extends across to the door.
